Description

Technical Field

[0001] The utility model belongs to the technical field of papermaking equipment, and in particular relates to dust removal equipment for paper processing. Background Art

[0002] Papermaking production includes two parts: pulping and papermaking. During the papermaking process, the cellulose on the surface of the paper will fall off from the paper due to friction to form paper fibers. The paper fibers will eventually be adsorbed on the surface of the paper and equipment and affect the quality of the final paper product. Therefore, the paper surface needs to be dusted during this process.

[0003] The announcement number is CN202121145502.5, and the patent name is a dust removal device for a papermaking equipment production line. It discloses a mobile mechanism arranged parallel to one side of the papermaking production line, and a dust removal air supply mechanism and a cantilever are fixedly installed on the upper end of the mobile mechanism. The cantilever is arranged close to the papermaking production line, and a dust collecting hood is fixedly installed on the upper end of the cantilever. The dust collecting hood is arranged directly above the papermaking production line. The dust collecting hood has the following technical features: by setting the dust collecting hood, the input end of the dust removal air supply mechanism can remove the paper blown off the papermaking production line through the dust collecting hood. The invention has the technical characteristics of collecting paper hair and dust, thereby preventing the paper hair and dust blown away from the papermaking equipment from escaping in the air, and ensuring the cleanliness of the papermaking equipment production line. However, it has the defect that when the dust is removed from the surface of the paper, the dust hood generates an adsorption force when removing dust from the paper, and since the paper cannot be effectively limited during the transmission process, the paper shakes during the dust removal process, and may even leave the papermaking production line and affect the dust removal of the paper. Therefore, the applicant has proposed a better technical solution to solve the above technical problems in view of the above defects.

The dust removal chamber 2 is arranged at the upper end of the support frame 1. A conveying mechanism 3 is arranged on the inner walls of the left and right sides of the support frame 1, and the two conveying mechanisms 3 are arranged correspondingly. The limiting mechanism 4 includes a base 41, two telescopic components 42 and a rolling rod 43. The base 41 is arranged on the inner wall of the support frame 1 above the conveying mechanism 3. The two telescopic components 42 are respectively arranged on both sides of the lower end surface of the base 41. The rolling rod 43 is rotatably connected to the two A conveying area 100 for conveying paper is formed between the telescopic components 42, and between the rolling rod 43 and the conveying mechanism 3; specifically, the rolling rod 43 is initially pressed against the conveying mechanism 3, and rotates when the conveying mechanism 3 is driven. When the paper enters the dust removal chamber 2 along the conveying area 100, the rolling rod 43 is pressed against both sides of the paper by the telescopic component 42, so as to ensure that the paper remains stable during the adsorption and dust removal, and is not prone to shaking or the situation that the paper is separated from the conveying mechanism 3 is avoided, thereby ensuring the normal operation of the equipment and improving the dust removal effect.

[0026] In this embodiment, refer to Figures 2 to 4The telescopic assembly 42 includes a connecting plate 421 and two telescopic parts 422. The connecting plate 421 is rotatably connected to the rolling rod 43. The two telescopic parts 422 are arranged at intervals on the upper end surface of the connecting plate 421, and one end thereof away from the connecting plate 421 is connected to the lower end surface of the base 41. The setting of the two telescopic parts 422 plays a role in balancing the rolling rod 43, and at the same time can effectively support the connecting plate 421 to ensure the stability of the rolling rod 43 during rotation.

[0027] Specifically, the telescopic member 422 includes a cylinder 4221, a slide 4222 and a pressure spring 4223. The cylinder 4221 and the slide 4222 are respectively arranged on the base 41 and the connecting plate 421, and the slide 4222 is inserted in the cylinder 4221. The pressure spring 4223 is arranged in the cylinder 4221, and its two ends are respectively connected to the slide 4222 and the inner end of the cylinder 4221; specifically, during the conveying process, the paper acts on the slide 4222 through the pressure spring 4223, and the slide acts on the rolling rod 43 through the connecting plate 421, so that the rolling rod 43 can be used to form a pressing force on both sides of the paper to limit its shaking during the adsorption and dust removal.

[0028] In this embodiment, refer to Figure 3 There are multiple limiting mechanisms 4, and the multiple limiting mechanisms 4 are arranged above the conveying mechanism 3 at intervals; the number of limiting mechanisms 4 can be determined according to the size of the paper. When the limiting mechanisms 4 are specifically set, a single limiting mechanism 4 can be correspondingly set on the driving roller of the conveying mechanism 3, effectively preventing the rolling rod 43 from crushing the conveyor belt on the conveying mechanism 3, thereby improving the use efficiency of the conveying mechanism 3.

[0033] The utility model provides a dust removal device for paper processing. When it is used, the rolling rod 43 is initially pressed against the conveying mechanism 3 and rotates when the conveying mechanism 3 is driven. When the paper enters the dust removal chamber 2 along the conveying area 100, the rolling rod 43 is pressed against both sides of the paper by the telescopic component 42. Specifically, during the conveying process, the pressure spring 4223 acts on the sliding column 4222, and the sliding column acts on the rolling rod 43 through the connecting plate 421. The rolling rod 43 can be used to form a pressing force on both sides of the paper to limit the shaking of the paper during the adsorption and dust removal. The paper is conveyed to the bottom of the dust removal chamber 2 along the conveying mechanism 3, and the dust removal chamber 2 can collect paper hair and dust on the surface of the paper through the dust collector. The utility model adopts a limiting mechanism 4 set on the conveying mechanism 3. During the conveying process of the paper on the conveying mechanism 3, the limiting mechanism 4 can be used to press and limit both sides of the paper, which can ensure that the paper remains in a stable state during the adsorption and dust removal, so that it is not easy to shake or avoid the situation that the paper is separated from the conveying mechanism 3, thereby ensuring the normal operation of the equipment and improving the dust removal effect.
